G350 SD Card: 64 GB vs 128 GB, Which Should You Get?

No internal storage: everything runs from microSD

The G350 has no built-in storage at all. Everything you see on screen, from the menu to your game files, is read from a microSD card. The console has two card slots, one on each side. On the left, the TF1/INT slot holds the system card, which contains the factory 64-bit Linux and its EmulationStation menu. On the right, the TF2/EXT slot takes a card just for games. This split has a real advantage: you can swap, clear or upgrade your games card without touching the card that boots the console.

The direct result: with no card in the left slot, the console has nothing to start. So the system card is not just a place for files. It is part of how the console works, just like the battery. Handle it with care, avoid pulling it out while the console is on, and never format it out of habit. The formatting tips in this guide apply to the games card, not the system card.

What card size changes, and what it doesn't

A card's capacity decides how many files you can keep on the console. It does not make any game run smoother. Performance comes from the hardware: the quad-core Rockchip RK3326 processor, the Mali-G31 MP2 graphics chip and 1 GB of RAM. This hardware handles 8-bit and 16-bit consoles, classic arcade, handhelds like the GBA and a large part of the PS1 library very well. For N64, PSP, Dreamcast and NDS, results depend heavily on the game and the settings, whatever the card size.

As for the upper limit, the manufacturer states support for cards up to 256 GB. Beyond that, nothing is guaranteed, and a card much bigger than you need adds nothing. Also keep in mind that a slow or worn-out card can make copying from your computer and some loading take longer, but it will never improve emulation. So the right rule stays simple: pick the space your library actually needs, plus a little extra.

Why a 64 GB card shows less than 64 GB

Usable space after formatting is always lower than the capacity printed on the card. There are two reasons. Card makers count in billions of bytes, while most operating systems count in multiples of 1,024, so the same amount of space looks smaller on screen. On top of that, the file system itself takes up a little room. On the system card, the factory Linux and its files use up some more space. That is not a defect or a scam, as long as the gap is a few gigabytes. A huge gap, on the other hand, is a red flag.

According to the manual, the games card in the TF2/EXT slot should use FAT32. Many cards of 64 GB and up ship in a different format, so you will often need to reformat your games card before filling it. Depending on your computer, the built-in tool may not offer FAT32 at these sizes: a dedicated formatting utility solves that. Formatting erases everything, so copy off whatever is on the card first. FAT32 also caps each file at 4 GB, which is still plenty for a PS1 disc image.

64 GB or 128 GB: it depends on what you emulate

File sizes vary a lot depending on the original system. A game for an 8-bit or 16-bit console usually weighs anywhere from a few kilobytes to a few megabytes. Even a large library from these systems takes up little space, so a 64 GB card leaves plenty free. PS1 disc images are a different scale: a single one can run several hundred megabytes, and some games span multiple discs. PSP, NDS and Dreamcast files are also much larger than 8-bit and 16-bit games.

In practice, 64 GB works well if you mostly play 8-bit and 16-bit consoles, classic arcade and handhelds, plus a few PS1 games. A 128 GB card makes sense if PS1 is a big part of your collection, or if you want to try heavier games whose performance varies from title to title. Whatever you choose, only copy games you have the rights to.

Name-brand cards and backing up your system card

A name-brand card from a reputable seller is not a luxury. Counterfeit cards sometimes report a capacity they don't really have: everything looks fine until new files overwrite old ones, or vanish. Other low-quality cards wear out quickly with repeated writes, such as game saves. On a console with no internal storage, that directly affects your progress. Before filling a new card, a capacity-testing tool run from a computer lets you check that it really delivers what it claims.

The system card deserves one extra step: a full backup. If it fails, the console won't boot, and whatever is on it may be lost too. An image of the card saved on a computer lets you start over on a new card. This backup is essential before trying a community system such as ArkOS or ROCKNIX, since switching is done at your own risk.

• Turn off the console, then remove the card from the TF1/INT slot.
• Create a full image of the card with disk imaging software on your computer.
• Keep that image in two places, for example your computer and an external drive.
• Also back up your game save files separately.
• Put the card back in the same slot before turning the console on.

What the G350 shop sells today

The G350 shop, an independent retailer, sells the 64 GB version, which the supplier describes as including a microSD card of that size, as seen in published unboxings. A 128 GB version will only be offered if a name-brand card is confirmed: a reliable, reasonable capacity beats a large card of uncertain origin. The price is shown on the product card, with free shipping.

If 64 GB feels tight, there's no need to wait for another version. The TF2/EXT slot lets you add your own name-brand games card later, formatted as FAT32 according to the manual, up to 256 GB according to the manufacturer. Your system card stays in place, untouched, and your backup image keeps its full value. That is often the simplest way to grow a PS1-focused library.
